NPE while running "log:tail" from Karaf console
Hi Karaf folks,
I'm experiencing occasional NPE while running "log:tail" in Karaf console.
Karaf version : 4.1.0
Exception in thread "pool-51-thread-1" java.lang.NullPointerException
at
org.apache.karaf.log.core.internal.layout.PatternParser$MDCPatternConverter.convert(PatternParser.java:551)
at
org.apache.karaf.log.core.internal.layout.PatternConverter.format(PatternConverter.java:63)
at
org.apache.karaf.log.core.internal.LogEventFormatterImpl.format(LogEventFormatterImpl.java:117)
at
org.apache.karaf.log.command.DisplayLog.printEvent(DisplayLog.java:121)
at
org.apache.karaf.log.command.DisplayLog.printEvent(DisplayLog.java:105)
at
org.apache.karaf.log.command.LogTail$PrintEventThread.run(LogTail.java:113)
at
java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)
at
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
at java.lang.Thread.run(Thread.java:745)
This occurs few times per day, it has no real impact other then tailing of
log is stopped (and must be restarted by CTRL+C, log:tail)
Google search didn;t yield anything related to this stacktrace.
Does anyone experience similar problem?
Thanks,
Richard.

Could you raise a JIRA issue, that should be an easy fix.
